The Lowdown
Right, let’s have a look at what’s on the cards for the next couple of weeks. The main event is Jaconé, and it’s got a bit of everything – some promising windows, but plenty of messy spells to wade through too.
The first real standout comes early, on Monday the 7th. The afternoon session is where it’s at: a solid 8ft swell from the SSW, with a 10-second period, and the wind goes glassy. That’s proper clean conditions, and the wave energy is strong (1113). This is for experienced surfers given the size, but it’s a cracking window. The water temp is about average for this time of year, so no surprises there.
The following morning, Tuesday the 8th, is next best. The swell drops to 5ft from the south, but you’ve got a clean 15 km/h offshore wind from the NE, and the energy is moderate (678). It’s a good, solid option for an intermediate. The afternoon is a bit smaller and less clean, so make the morning count.
Now, there’s a bit of a lull. Wednesday the 9th through Saturday the 12th sees the swell drop off and the winds get messy. Wednesday morning is glassy but only 4ft, and the energy is weak (367). Not worth getting excited about. The weekend is a write-off with onshore winds and poor conditions.
Things pick up again on Monday the 14th. The morning brings a 7ft south swell, a 10-second period, and a clean offshore NE wind at 10 km/h. The energy is moderate (942). It’s a solid, powerful session for anyone who can handle it. The afternoon is a step down, but still surfable.
The real highlight, though, is the Saturday the 19th. This is the one to circle. The morning has a 7ft south swell, a nice long 13-second period, and a clean offshore wind from the ENE at 15 km/h. The wave energy is strong (1670). This is a proper groundswell, and it’ll be lining up nicely. It’s going to be a bit big for beginners, but for the experienced lot, it’s a gem. Crowds are possible here, so get in early.
Sunday the 20th morning is also worth a mention – glassy conditions with a 4ft SSW swell and a 12-second period, energy moderate (652). It’s a clean, low-key option to round out the good run.
After that, the second week gets a bit flatter and windier, with only small, ordinary surf. The gap from the 21st onwards is a few days of nothing special. The 22nd has a tiny 2ft south swell with an offshore wind, but it’s weak and only just surfable.
So, the standout is the 19th, with the 7th and 14th as solid runners-up. Make the most of those windows.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
